[0034] The receiving assembly 10 includes an environmental chamber 11 and a supporting platform 12 disposed inside the environmental chamber 11. Water is distributed inside the environmental chamber 11. The supporting platform 12 is used to receive the test mold 01.

[0035] The circulation component 20 is provided outside the environmental chamber 11 and is used to control the circulation of water in and out of the environmental chamber 11;

[0036] The disturbance component 30 is provided at the bottom of the environmental chamber 11 and is used to stir the water inside the environmental chamber 11 and cause the water to be disturbed;

[0037] Among them, the circulation component 20 includes a pump body 21, an inlet pipe 22 and an outlet pipe 23. The pump body 21 is connected to the two opposite sides of the environmental chamber 11 through the inlet pipe 22 and the outlet pipe 23. The spoiler component 30 includes a controller 31 and multiple rotors 32. The controller 31 is arranged on the outer side of the bottom of the environmental chamber 11, and the multiple rotors 32 are rotatably arranged on the inner side of the bottom of the environmental chamber 11. The controller 31 and the multiple rotors 32 are electrically connected to realize the individual rotation of the rotor 32 or the synchronous rotation of multiple rotors 32.

[0038] The utility model provides a circulation component 20 so that water can circulate in and out of the environmental chamber 11, thereby ensuring the continuous flow of the water. The water is stirred and disturbed by the controller 31 and multiple rotors 32. The rotation mode of the rotors 32 can be adjusted as needed to achieve precise control of the degree of water disturbance. The circulation speed and disturbance intensity can be adjusted according to different test requirements to simulate the dynamic characteristics of different coastal environmental conditions, thereby improving the accuracy and reliability of the test results.

[0039] It should be noted that the test mold 01 contains test materials such as sea sand and microorganisms. Before conducting the test, the test materials to be tested can be placed in the selected test mold 01, and the test mold 01 and the test materials inside can be placed together on the supporting platform 12 inside the environmental chamber 11. According to the test requirements, the pump body 21 adjusts the flow rate of water in and out of the environmental chamber 11 through the water inlet pipe 22 and the water outlet pipe 23, and the controller 31 controls the rotor 32 to rotate alone or multiple rotors 32 at different positions to rotate synchronously and in combination to control the disturbance intensity of the water body, thereby simulating different coastal water environment conditions.

One end of the water outlet pipe 23 is connected to the water outlet 114, and the other end passes through the connection port 241 on the corresponding side and is arranged on the inner side of the transfer box 24. The setting of the transfer box 24 provides a stable installation environment for the pump body 21, and also prevents the water splashing during the operation of the pump body 21 from affecting the external environment.

[0044] Based on the above embodiment, a plurality of supporting feet 115 are further provided on the outside of the environmental chamber 11. The supporting feet 115 are located on the side of the bottom plate 111 away from the side plate 112 and are fixed at the four corners of the bottom plate 111.
